The public will be treated to acoustic renditions of Christmas carols and some of each artist's hit songs.

Australian singer and actress Jessica Mauboy said that she is "proud to be part of this year's Optus 'Carols for a Cause' and (she hopes they) can make this Christmas a little easier for those in need".

The events will take place between December 10th and December 14th and Optus will match every dollar raised at each event.

Optus will also be donating one dollar to the charities from sales made from the Optus Music Store for each artist during the week of performances.
